Sometimes, a complicated story.
Enterprise software is a beast. A unsexy unruly beast.
Sometimes, you go back into the platform to clarify some copy due to changes in the system. At the same time, you find some opportunities to clean up the UX and make things a little clearer for the user.
Of course, the director of product management then gives a one hour presentation on the feature and how it works. And then you realize it's not so simple. (Of course, it never is. Even when you want to change some copy.)
